Information disclosure via out-of-bounds UPR parsing
Published Aug 23, 2023 · Updated Oct 3, 2024
Out-of-bounds reads in Hitachi EH-VIEW Designer allow local users to disclose information by opening a malicious UPR file. Four flaws in the Designer UPR parser read beyond intended buffer boundaries when processing crafted file data. Exploitation requires a user to open the file; Hitachi has not disclosed the affected parser routines or the specific memory contents exposed.
